The hand-excavation of diamond-bearing volcanic pipe rock at Colesberg Kopje, Kimberley, Northern Cape, South Africa, using picks, shovels, and crowbars on small individually held claims -- collectively producing what is widely regarded as the largest hand-dug excavation in human history, 'the Big Hole.' Following the 1866-67 discovery of the Eureka diamond (found by 15-year-old Erasmus Jacobs on the family farm De Kalk, near Hopetown) and the 1869 discovery of the Star of Africa (found by a shepherd known only as Booi on the banks of the Orange River), diamonds were located at Colesberg Kopje on the De Beers brothers' farm Vooruitzigt in 1871, triggering a rush initially called New Rush before the settlement was renamed Kimberley in 1873. The land was divided into thousands of small privately held claims, documented at roughly 30 by 30 feet (approximately 3,200 full claims by the end of 1871, many further subdivided among individual and small-group diggers); miners excavated with picks, shovels, and crowbars, hauling material to the surface and sorting it by hand using sieves and sorting tables, all diamonds ultimately picked out by hand. As individual claims deepened at differing rates, a criss-crossing network of ropes, pulleys, and pipes connected the mine floor to the surface, and roadways preserved between claims for access gradually collapsed and merged as digging progressed, transforming the original kopje into a single coalescing pit. Early Kimberley diggers established their own self-governing regulations, documented as 'Diggers' Laws.' From mid-July 1871 to 1914, an estimated 50,000 miners worked the site by hand, removing approximately 22 million tons of earth and rock and yielding roughly 2,720 kilograms (13.6 million carats) of diamonds, before flooding and structural instability forced the transition to underground mining. The claim-based artisanal digging era directly gave rise to several of history's most significant mining fortunes and companies: Cecil John Rhodes arrived at the mines at age 17 and initially sold ice to miners to fund his first claim purchase; Barney Barnato bought four claims in 1876, forming the basis of the Barnato Diamond Mining Company; both men's claim consolidations were central to the eventual formation of De Beers Consolidated Mines, marking the historical transition from thousands of individual artisanal claim-holders to industrial corporate consolidation that has defined the global diamond industry ever since.
